Battlefield even though it has its times. Can't get over that 64 player conquest.
I thought Destiny would have been better but MM is basically like another CoD with a Sci-Fi/Fantasy layout. Don't get me wrong, the story is great but MM I'll give a 6/10. I'll be getting the game just for the story part of it. Really hoping its longer than I think it is or it will be collecting dust after I beat it. I'll actually be "thinking" about buying Destiny '2' when it comes around.

BF3 was really fun and I'd recommend picking it up for 20$ or whatever it'll be at gamestop. It still has an active community on all platforms and it has some really awesome multiplayer. Don't waste your cash on BF4, it's a broken mess with poor level design.
With that said, destiny is shaping up to be much more interesting.
